The native graphical user interface of GME is shown in the figure below. The picture shows a model of an signal flow graph loaded. In this simple model, only Models, Atoms and Connections are used. The window on the right hand side shows the Model Browser that displays the whole project in a tree-like fashion. The Aggragate tab displays the containment hierarchy, while the Inheritance tab shows the type inheritance hierarchy. The Meta tab provides an overview of the modeling paradigm specifications. The bottom window is the Part Browser where all the parts that are available in the current aspect of the current model are shown. Notice that two tabs indicate the aspects of the signal flow model: SignalFlow and Parameter.
